Application ja ar- 522, 1942, s iainoiizvnr f n 1 Claim. (ems-say I This invention relates to dental flasks of sec? 2- tional; construction adaptedifor holding artificial I teeth while being vulcanizedto dental. plates. 1

An object of the invention is itoprovide a-flask having separable elements so arrangedithat they set therein.

whereby the moulding material may entered or removed without fracture.

.7 Another purpose is to produce a" dental flask I of sturdy construction, easily and quickly operated r and capable-of long continued service.

, Finally, it is ,an aim to furnish a' fiask fparticularly adapted for use in connection with-iniproved dental plates described in my copending,
